Some games on your computer come with anti-cheat software that runs a driver in the Windows kernel, the lowest layer of the operating system; Riot Games' support page, checked on 8 November 2026, lists one as part of Vanguard and links to removal steps. A researcher reported on a blog in late October 2005 that XCP, the copy protection software on Sony BMG music CDs, hid files and running programs whose names began with a set prefix and had no entry in the Control Panel's Add or Remove Programs list. Sony BMG suspended the manufacture of XCP CDs as a precaution on 11 November 2005, according to a company statement quoted by Betanews, and on 18 November Sony Music Japan International announced it had asked dealers in Japan to stop selling 40 imported XCP titles and pull shop stock, PC Watch reported. In January 2007, the US Federal Trade Commission published a proposed settlement barring Sony BMG from installing copy protection software that consumers could not readily find or remove. On Windows, you can turn on memory integrity, which makes it harder for malicious programs to use drivers to take over your PC, under Device security > Core isolation details in the Windows Security app; if Windows reports an incompatible driver, Microsoft suggests asking the device manufacturer for an updated one.
